The older one is Xinglang, but the level of teachers is very average. I used to have Zhao Fenggang, but now I have gone to ccxx. So it is not very cost-effective to learn.

Is Tsinghua Wanbo OK? There is a good teacher. I don't know if he is still here. His name is Liu Bo, but it is not very large in Shenyang.

There is also a CCIE, located in the North Station, which is not very large. That CCIE's name is Li Xiaoming. I don't know her level.

On Sunday, you can visit Hao San Street or listen to Xinglang's open class. Whether you go or not is up to you.
